GREEN BLACK-CAPPED FLYCATCHER. 255 
low; upper parts of the wings, the tail, and back, yellow olive ; inte- 
rior vanes, and tips of the wing and tail, dusky; bill, black; legs, 
flesh colored ; inner webs of the three exterior tail-feathers, white for 
half their length from the tips; the next, slightly touched with white; 
the tail, slightly forked, and exteriorly edged with rich, yellow olive. 
The female has the throat and breast yellow, slightly tinged with 
‘blackish ; the black does not reach so far down the upper part of the 
neck, and is not of so deep a tint. In the other parts of her-plumage, 
she exactly resembles the male. I have found some females that had 
little or no black on the head or neck above, but these I took to be 
young birds, not yet arrived at their full tints.

SETOPHAGA? WILSONTI, —JarvinE.* 
Sylvia Wilsonii, Bonap. Synop. p. 86. — Nomenclature, No. 127. 
Tuis neat and active little species I have never met with in the 
works of any European naturalist. It is an inhabitant of the swamps 
of the Southern States, and has been several times seen in the lower 
parts of the states of New Jersey and Delaware. Amidst almost 
unapproachable thickets of deep morasses it commonly spends its time 
during summer, and has a sharp, squeaking note, no wise musical. It 
leaves the Southern States early in October. 
This species is four inches and a half long, and six and a half in 
extent; front line over the eye, and whole lower parts, yellow, brightest 
over the eye, and dullest on the cheeks, belly, and vent, where it is 
tinged with olive; upper parts, olive green; wings and tail, dusky 
brown, the former very short; legs and bill, flesh colored; crown, 
covered with a patch of deep black; iris of the eye, hazel. 
The female is without the black crown, having that part of a dull 
yellow olive, and is frequently mistaken: for a distinct species. From 
her great resemblance, however, in other respects, to the male, now 
first, figured, she cannot hereafter be mistaken. 
* The Prince of Musignano has never seen this species, but was of opinion that 
it would prove a Sylvia; and the specific name being preoccupied, be chose that 
of its'discoverer. I have retained his specific name, though the reason of the change 
will not now be available. The services of Wilson, however, can s*arcely = 
overpaid, and the reputation of no one is here implicated. — Ep.
